  • Method of enhancing in-service structural performance of a sheet metal component
    Patent number: 9771110
    Abstract: A method is provided for enhancing in-service structural performance of a sheet metal component incorporating a discontinuity. The method comprises heat-treating a zone of the sheet metal component a predetermined distance from the discontinuity thereby changing the strength and ductility of the zone and shifting the deformation induced in the sheet metal component by a subsequent deformation event away from the discontinuity to the zone.
    Type: Grant

  • HOT-STAMPING TAILOR-WELDED BLANKS OF ALUMINUM SHEET
    Publication number: 20160030992
    Abstract: Forming a tailor-welded blank (TWB) having aluminum sheets includes various elements. For example, a hot-stamping methodology is applied to a welded blank for meeting load and stiffness requirements in tandem to weight efficiency. A TWB can result in improved material utilization, and applying the hot-stamping methodology can improve the formability of the TWB. After forming and subsequent processing, a peak-age heat treatment is utilized such that a lightweight, high strength part may be attained.
